Crystal Hexamine

Crystal Hexamine

Hexamine
• We produce two kinds of hexamine: powder and crystal appearance, three specifications: Fine powder, Unstabitily and Stabitily (add antiblockingagent) .Most factory just produce unstabitily type,powder appearance, which easily block for a longer time. While for Stabitily hexamine, large particles crystal appearance ,also add 0.2%-0.3% antiblockingagent can go through long time stored and transport, but no block. We are unique and first one who own this technique.
